At high temperatures, the absorbed hydrogen tends to gather in the grain boundaries and stress-induced cracking is then intergranular. If the metal is under a high tensile stress, brittle failure can occur. Search for other works by this author on: © 1965 National Association of Corrosion Engineers.

How to Prevent Hydrogen Embrittlement. If the presence of hydrogen sulfide causes entry of hydrogen into the component, the cracking phenomenon is often termed “sulphide stress cracking (SSC)”. Hydrogen diffuses along the grain boundaries and combines with the carbon, which is alloyed with the iron, to form methane gas. You could not be signed in. Austempered iron is also susceptible, though austempered steel (and possibly other austempered metals) display increased resistance to hydrogen embrittlement. Hydrogen Embrittlement of Stainless Steel. Type 310 stainless steel in thin sections was embrittled by hydrogen. It is the latter that concerns the nuclear industry. metals, differing only in that at low temperatures and relatively high strain rates complete recovery in ductility was not achieved. Hydrogen embrittles a variety of substances including steel, aluminium (at high temperatures only ), and titanium. Type 310 stainless steel in thin sections was embrittled by hydrogen.

Hydrogen entry, the obvious pre-requisite of embrittlement, can be facilitated in a number of ways summarized below: (Defence Standard 03-30, October 2000). Hydrogen embrittlement occurs in a number of forms but the common features are an applied tensile stress and hydrogen dissolved in the metal. a. by some manufacturing operations such as welding, electroplating, phosphating and pickling; if a material subject to such operations is susceptible to hydrogen embrittlement then a final, baking heat treatment to expel any hydrogen is employed. Recent research activities on hydrogen embrittlement, especially Hydrogen Environment Embrittlement (HEE) susceptibility of stainless steels in highly pressurized gaseous hydrogen environments were reviewed from the viewpoints of effects of chemical compositions, hydrogen … Microbiologically Influenced Corrosion (MIC). Sources of hydrogen causing embrittlement have been encountered in the making of steel, in processing parts, in welding, in storage or containment of hydrogen gas, and related to hydrogen as a contaminant in the environment that is often a by-product of general corrosion.

The cracking of martensitic and precipitation hardened steel alloys is believed to be a form of hydrogen stress corrosion cracking that results from the entry into the metal of a portion of the atomic hydrogen that is produced in the following corrosion reaction. Hydrogen Embrittlement of Stainless Steel. If stress induces cracking under these conditions, the path is transgranular.
